Description
Technical field
The present invention relates to the product based on calcium sulfate of improved fire resisting, change in particular it relates to have after high temperature
The building based on calcium sulfate/structure product of kind intensity.
Background technology
Product based on calcium sulfate is widely used in structure building, for example, forming indoor partition (uses wallboard, also referred to as
Dry wall, plasterboard or plaster board) and ceiling or parcel building in pipeline (for example, ventilation shaft).
Product such as wallboard based on calcium sulfate are generally by drying in two sulfuric acid between mounting cardboard or fiberglass packing
Semihydrate (the CaSO of calcium4·1/2H2O), the gypsum or the water paste of plaster also referred to as calcined and formed.As slurry is dry
Dry and calcining gypsum forms the hard, rigid plaster (calcium sulfate dihydrate being clipped between interior lining panel/pad by aquation
(CaSO4·2H2O)) core.
When wallboard is exposed to high temperature, such as the high temperature undergone in building fire or the pipe that high temperature fluid is carried for wrapping up
During the high temperature that the wallboard in road is subjected to, the crystallization water included in gypsum is displaced, and produces the anhydrite of calcium sulfate.Originally, this has
Following advantage, the i.e. heat transfer across wallboard are reduced, therefore help to be produced during comprising the heat or building fire distributed from pipeline
Raw heat.But, at a temperature of about 400~450 DEG C, the AIII phases anhydrite (also referred to as γ-CaSO originally formed4Or " can
Dissolubility " anhydrite) AII phases (or " insoluble " anhydrite) are changed into, the phase transformation causes the contraction of wallboard, i.e. dimensional stability
Loss.The contraction (its be probably wallboard length or width about 2%, or about 6vol%) generally cause wallboard away from them
Supporting construction.This is clearly undesirable.In the case where wallboard is used for indoor partition and breaks out fire, contraction can leave sky
Gap so that with the neighbouring room of burning things which may cause a fire disaster exposed to hot/fiery influence.Space also causes oxygen to enter burning things which may cause a fire disaster, hence in so that fire burning
And any fire resistant doorsets is failed.
At higher temperature (more than 600 DEG C), anhydrite Ⅱ sintering causes wallboard volume to be substantially reduced.This leads
Great amount of contraction is caused, it ultimately causes caving in for interior wall/ceiling/pipe sleeve, because they are no longer by their support
Structure is kept.
In addition, once the chemical composition of gypsum is changed by heat, then wallboard loses intensity, and finally loss structure is complete
Property.Generally, the gypsum core of the wallboard of the high temperature produced during such as building fire is broken into fine dust, therefore wallboard is actually
Can fragmentation.
Product based on calcium sulfate is also used for casting metal object or glass object.Melting is filled in calcium sulfate mould
Before glass/metal, 700~900 DEG C are heated to.Importantly, the high temperature of the such mould based on calcium sulfate of control
Shrink, to ensure that mould is non-leakage and ensure that the glass/metal product of casting is not bent.
In order to improve the water resistance of product, the silicone oil comprising low content is known in the product based on calcium sulfate.
Currently preferred target is to provide the product based on calcium sulfate for improving fire resistance/heat resistance, and it is hot sudden and violent
After dew, for example, having improved intensity, hardness and structural intergrity during building fire.Such improved fire resistance production
Product can have following specific purposes：As building products, for example, form indoor partition wallboard or panel, smallpox in building
Pan tile block, the wallboard for wrapping up ventilation equipment/air draft pipe or panel, the joint filler for combining wallboard/panel/tile fragment
Or the mould cast for glass/metal product.
